(svn r11579) -Revert(r11578): some cases of key propagation are not handled correctly.
A better solution will be deviced, but not now. Let's not cause a ton of bug reports

(svn r11578) -Codechange: Introduce the window default flag WDF_TEXTENTRY which specifies that the window holding it is actually one that enables an edit box.
Use this flag when dispatching a key event instead of using some hard coded window IDs.
This should ease a little bit the creation of new edit aware windows.

(svn r11551) -Codechange: Introduction of widget control members on struct Window. These "new" members have the exact same functionalities as their pure functions "genitors"
Ex: "Window::SetWidgetLoweredState(byte widget_index, bool lowered_stat)" is the member corresponding to "SetWindowWidgetLoweredState(Window *w, byte widget_index, bool lowered_stat)"

(svn r11256) -Codechange: Make opening a new toolbar not overlapping its parent one, by locating it under the parent, and aligned with the left side of it.
FS#1310, by BigBB

(svn r10705) -Fix (r10704): some windows were not correctly initialized as they resized the window themselves and that should be interfered by making sure the window is resized in the right "step" size.
-Fix (r10704): call the WE_RESIZE when resizing during initialization of the windows.

(svn r10276) -Codechange: made a counter based on milliseconds and independent of the game-state to base double-click and TGP Generation Process on
-Codechange: renamed _timer_counter to _palette_animation_counter, as that is what it is

(svn r10190) -Codechange: merged renderer and blitter to one single class API: blitter
-Codechange: introduced a hierachy of blitters to avoid a lot of code duplication
Note: this allows much easier adding other types of video-drivers, like OpenGL

(svn r10121) -Codechange: split renderer from rest of code; no longer any code directly accesses the video-buffer
-Add: added NULL blitter and renderer, which are always used for -vnull
-Add: dedicated driver doesn't blit nor render by default. Can be overruled by user. (-D -b 8bpp-optimized)
-Remove: removed CTRL+D from win32, which is incompatible with above
-Add: extended screenshot support for PNG and BMP
-Codechange: remove all hardcoded 8bpp references and replace them with more dynamic ones
-Codechange: minor stuff in blitters

(svn r9846) -Codechange: introduced ZOOM_LVL_MIN and ZOOM_LVL_MAX for the obvious reasons
-Codechange: introduced ZOOM_LVL_DETAIL to show/remove details
-Codechange: changed << and >> operator with ZoomLevel to a simple wrapper (that in theory also allows zoom-in besides the current zoom-out)
-Fix r9845: missed some int -> ZoomLevel

(svn r9844) -Codechange: replace zoomlevel with an enum
-Codechange: use predefined enums for viewport zoomlevels

(svn r9126) -Feature: "Function of scrollwheel" can now be set to off as well
Note: since this can be useful for all platforms, the GUI is no longer OSX specific.
Note: scrolling lists is still unaffected by this setting

(svn r9111) -Feature: [OSX] mighty mice and touchpads can now scroll the map (in all directions)
It has to be enabled first (in patches->interface) first and this will disable scrollwheel zooming
Note: patch setting "Map scrollwheel speed" might need to be changed since the "correct" setting
appears to depend on what kind of mouse is in use (mighty mouse or touchpad)

(svn r9034) -Codechange: renamed _pause to _pause_game, as some targets already have
a symbol called _pause (and therefor our variable conflicts with
thatone. We shouldn't be using _ as global indicator.....)
